Botkit template
This project implements a Botkit + Webex adapter bot, based on the generator-botkit Yoeman template, providing a few extra good-practice features, plus several interesting samples:
-
Optionally use Webex Node.js SDK websockets for incoming events and messages, instead of webhooks
-
A 'health check' URL: check bot availability, uptime and metadata by browsing to the bot's public URL
-
Quality-of-life features: fallback/catch-all module; welcome message when user joins a space
-
'Help' command auto-generation function
-
Redis/MongoDB storage support for persistent/scalable storage of conversation state
-
checkAddMention() function to automatically format bot commands for 1:1 or group space usage
Websockets vs. Webhooks
Most Botkit features can be implemented by using the Webex JS SDK websockets functionality, which establishes a persistent connection to the Webex cloud for outbound and inbound messages/events.
Webex also supports traditional HTTP webhooks for messages/events, which requires that your bot be accessible via a publically reachable URL. A public URL is also needed if your bot will be serving any web pages/files, e.g. images associated with the cards and buttons feature or the health check URL.
- If you don't need to serve buttons and cards images, you can set the environment variable
WEBSOCKET_EVENTS=True
and avoid the need for a public URL - If you are implementing buttons & cards, you will need a public URL (e. g. by using a service like Ngrok, or hosting your bot in the cloud) - configure this via the
PUBLIC_URL
environment variable
How to run (local machine)
Assuming you plan to us ngrok to give your bot a publically available URL (optional, see above), you can run this template in a jiffy:
-
Clone this repo:
git clone https://github.com/CiscoDevNet/botkit-template.git cd botkit-template
-
Install the Node.js dependencies:
npm install
-
Create a Webex bot account at 'Webex for Developers', and note/save your bot's access token
-
Launch Ngrok to expose port 3000 of your local machine to the internet:
ngrok http 3000
Note/save the 'Forwarding' HTTPS (not HTTP) address that ngrok generates
-
Rename the
env.example
file to.env
, then edit to configure the settings and info for your bot.Note: you can also specify any of these settings via environment variables (which will take precedent over any settings configured in the
.env
file) - often preferred in production environments.To successfully run all of the sample features, you'll need to specify at minimum a
PUBLIC_URL
(ngrok HTTPS forwarding URL), and aWEBEX_ACCESS_TOKEN
(Webex bot access token).If running on Glitch.me or Heroku (with Dyno Metadata enbaled), the
PUBLIC_URL
will be auto-configured.Additional values in the
.env
file (likeOWNER
andCODE
) are used to populate the healthcheck URL meta-data.Be sure to save the
.env
file! -
You're ready to run your bot:
node bot.js
Quick start on Glitch.me
-
Delete the
.env
file that Glitch created automatically -
Rename
.env.example
to.env
, then open it for editing.Find the
WEBEX_ACCESS_TOKEN
variable, paste in your bot's access tokenOptional: enter appropriate info in the "Bot meta info..." section
Note that, thanks to the Glitch
PROJECT_DOMAIN
env variable, you do not need to add aPUBLIC_URL
variable pointing to your app domain
You bot is all set, responding in 1-1 and 'group' spaces, and sending a welcome message when added to a space!
You can verify the bot is up and running by browsing to its healthcheck URL (i.e. the app domain.)
Quick start on Heroku
-
Create a new project pointing to this repo.
-
Open your app's Settings tab, and reveal your Config Vars
-
Add a
WEBEX_ACCESS_TOKEN
variable with your bot's access token as value -
Add a
PUBLIC_URL
variable pointing to your app's Heroku URLIf your app is using Dyno Metadata, the public URL will be detected automatically
-
In the upper right under the More dropdown, select Restart all dynos
You bot is all set! You can invite it to 1-1 and 'group' spaces, see it sending a welcome message when added, and responding to commands (try help
.)
You can always verify the bot is operational by browsing to its healthcheck URL (i.e. the app domain.)
